This book was released on 2004 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: The steady growth of commercial truck travel has led to an increasing demand for truck parking spaces at public rest areas and private truck stops on interstate highways in Virginia. This study developed a methodology to determine the supply and demand for commercial truck parking along these corridors. Supply was defined as the number of parking spaces available for commercial truck parking, and demand was defined as the sum of the parking accumulation and illegal parking at a given time. Phase I of this study developed a methodology to determine the supply and demand for commercial truck parking using I-81 in Virginia as a case study. This Phase II study expanded the study to other interstate highways in Virginia, checked the applicability of the parking demand model developed in Phase I, and developed new models when necessary. Extensive data on the characteristics of commercial truck parking and the characteristics of each truck stop and rest area were collected. In addition, truck drivers and truck stop owners/operators were surveyed. The data collected were used to develop models to describe the relationship between parking accumulation and independent variables such as traffic volume on the highway, truck percentage, parking duration, and the distance from a highway to a truck stop. After the applicability of the models was tested, they were used to estimate commercial truck parking demand in 2010 and 2020. Deficiencies of parking spaces with respect to estimated demand were then determined for each truck stop and the entire Virginia interstate highway system. The results indicate that the demand for commercial truck parking at individual truck stops on I-95 exceeds the supply by 10 to 22 percent and that there is no commercial parking shortfall at truck stops along I-64, 1-77, and I-85. However, there are shortfalls at rest areas on I-66, I-77, I-85, and I-95, varying from about 6 percent on I-85 to about 32 percent on I-95. If no new parking spaces are provided and a 5 percent increase in truck travel is assumed, the demand/supply ratio in 2010 for large truck parking on all interstate highways in Virginia will exceed 1.00. This deficiency could be as high as 40 percent on I-95.

This book was released on 2002 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increasing number of trucks traveling on Virginia highways has led to a growing demand for public rest areas and private truck stops. This study developed a methodology to determine the supply and demand for commercial heavy truck parking using I-81 in Virginia as a case study. In this study, supply was defined as the number of parking spaces available for large truck parking, and demand at a given time was defined as the sum of the parking accumulation and the illegal parking. Extensive data on the characteristics of large truck parking including parking duration and accumulation for different times of day were obtained. Data were obtained at 14 public rest areas and 29 private truck stops. Detailed information was also obtained on the characteristics of each truck stop and rest area, including the location; number and types of parking spaces; and availability of other facilities, such as restaurants and showers. Two types of questionnaire surveys were conducted. The first involved truck drivers, and the second involved truck stop managers/owners. The data collected were used to develop models to describe the relationship between parking accumulation and independent variables such as traffic volume on the highway, truck percentage, parking duration, and the distance of a truck stop from the interstate. The models developed were then used to estimate demand in 10 and 20 years. Any shortfall in supply with respect to the estimated demand was then determined for each truck stop and the entire highway. The results indicated that the existing maximum demand is 2,947 parking spaces, which exceeds the supply by 309 spaces. This deficiency will increase to 1,193 and 1,463 spaces in 2010 and 2020, respectively, if the number of parking spaces for large trucks does not increase.

Book Synopsis Behavioural Adaptation and Road Safety by : Christina Rudin-Brown
Download or read book Behavioural Adaptation and Road Safety written by Christina Rudin-Brown and published by CRC Press. This book was released on 2013-05-24 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite being an accepted construct in traffic and transport psychology, the precise nature of behavioural adaptation, including its causes and consequences, has not yet been established within the road safety community. A comprehensive collection of recent literature, Behavioural Adaptation and Road Safety: Theory, Evidence, and Action explores behavioural adaptation in road users. It examines behavioural adaptation within the context of historical and theoretical perspectives, and puts forth tangible—and practical—solutions that can effectively address adverse behavioural adaptation to road safety interventions before it occurs. Edited by Christina Rudin-Brown and Samantha Jamson, with chapters authored by leading road safety experts in driver psychology and behaviour, the book introduces the concept of behavioural adaptation and details its more relevant issues. It reviews the definition of behavioural adaptation that was put forward by the OECD in 1990 and then puts this definition through its paces, identifying where it may be lacking and how it might be improved. This sets the context for the remaining chapters which take the OECD definition as their starting points. The book discusses the various theories and models of behavioural adaptation and more general theories of driver behaviour developed during the last half century. It provides examples of the "evidence" for behavioural adaptation—instances in which behavioural adaptation arose as a consequence of the introduction of safety countermeasures. The book then focuses on the internal, "human" element and considers countermeasures that might be used to limit the development of behavioural adaptation in various road user groups. The book concludes with practical tools and methodologies to address behavioural adaptation in research and design, and to limit the potential negative effects before they happen. Supplying easy-to-understand, accessible solutions that can be implemented early on in a road safety intervention’s design or conception phase, the chapters represent the most extensive compilation of literature relating to behavioural adaptation and its consequences since the 1990 OECD report. The book brings together earlier theories of behavioural adaptation with more recent theories in the area and combines them with practical advice, methods, and tangible solutions that can minimise the potential negative impact of behavioural adaptation on road user safety and address it before it occurs. It is an essential component of any road safety library, and should be of particular relevance to researchers, practitioners, designers, and policymakers who are interested in maximizing safety while at the same time encouraging innovation and excellence in road transport-related design.

This book was released on 2016-09-12 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are approximately 4,000 fatalities in crashes involving trucks and buses in the United States each year. Though estimates are wide-ranging, possibly 10 to 20 percent of these crashes might have involved fatigued drivers. The stresses associated with their particular jobs (irregular schedules, etc.) and the lifestyle that many truck and bus drivers lead, puts them at substantial risk for insufficient sleep and for developing short- and long-term health problems. Commercial Motor Vehicle Driver Fatigue, Long-Term Health and Highway Safety assesses the state of knowledge about the relationship of such factors as hours of driving, hours on duty, and periods of rest to the fatigue experienced by truck and bus drivers while driving and the implications for the safe operation of their vehicles. This report evaluates the relationship of these factors to drivers' health over the longer term, and identifies improvements in data and research methods that can lead to better understanding in both areas.
Book Synopsis Exclusive Lanes for Trucks and Passenger Vehicles on Interstate Highways in Virginia by : Lester A. Hoel
Download or read book Exclusive Lanes for Trucks and Passenger Vehicles on Interstate Highways in Virginia written by Lester A. Hoel and published by . This book was released on 1997 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increases in heavy truck traffic on Virginia's highways in recent years have raised concerns about both safety and capacity, particularly on the interstate system. Transportation agencies have developed a number of strategies for dealing with the impacts on safety and capacity of a truck population that has been increasing in volume and in the percentage of large tractor-trailers. One strategy that has been suggested is separate lanes for trucks and passenger vehicles. A reliable methodology to determine when separate lanes for trucks and passenger vehicles are economically feasible would enable transportation officials to make informed decisions concerning when this approach should be considered and used. This study evaluated a computer program, Exclusive Vehicles Facilities (EVFS), developed by the Federal Highway Administration for determining the economic feasibility of separating trucks and other vehicles on freeway segments. A 50.7-km (31.5-mi) segment of 1-81 in Virginia was selected to demonstrate the application of the program. A number of factors contribute to the feasibility of exclusive lanes. Although no single factor predominates, traffic volume, vehicle mix percentage, accident rates, and maintenance and construction costs are given more weight than other factors in the program. Among the program's strengths are its ability to analyze a number of alternatives for a variety of different conditions, its ease of use, and the fact that it can be inexpensively applied. Its weaknesses include its inability to differentiate between the lane(s) (i.e., inside, middle, outside) to which restrictions are applied and its unsuitability for analyzing exclusive lane alternatives in which a barrier is used to separate vehicle types. With respect to 1-81, several exclusive lane strategies produced a benefit-cost ratio greater than 1.0 and a net present worth in the millions of dollars. Should 1-81 or another high-volume interstate corridor with a large truck percentage be considered for improvement, VDOT should apply EVFS to assist in evaluating the feasibility of exclusive lane alternatives. Since EVFS is designed to perform economic analyses, operational and geometric implications of any exclusive lane strategy should also be considered.

Book Synopsis Evaluation of Truck Lane Restrictions in Virginia by : Michael D. Fontaine
Download or read book Evaluation of Truck Lane Restrictions in Virginia written by Michael D. Fontaine and published by . This book was released on 2009 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: Virginia, like many other states, has used truck lane restrictions on parts of its interstate system in an attempt to improve mobility and safety. The Code of Virginia currently specifies two types of lane restrictions. First, trucks may not travel in the left-most lane of interstates with three or more lanes by direction (1) when the speed limit is 65 mph or higher, (2) along all of I-81, and (3) along interstates in the Virginia Department of Transportation's (VDOT) Northern Virginia District. Second, trucks may not travel in the left lane of two-lane directional interstate segments when their speed is below the posted speed limit; this restriction was enacted in 2007 and was intended to reduce cases of trucks impeding traffic flow on steep grades in the western part of the state. This report describes Phase II of a 2007 study that found that the safety impact of the first type of restriction appeared to be affected by traffic volume. Safety was enhanced on low- volume roads (i.e., annual average daily traffic [AADT] less than 10,000 vehicles per day per lane [vpdpl]) but degraded on high-volume roads (i.e., AADT above 10,000 vpdpl). Given that most of the high-volume interstates investigated were in Northern Virginia, there was a need to re-examine the safety analysis to ensure that the findings were not a product of the growing congestion in the region but rather were attributable to the effects of the truck lane restrictions. The purpose of this study was to provide a detailed assessment of the safety and mobility impacts of Virginia's truck lane restrictions, expanding on the Phase I study. First, crashes on high-volume interstates with three or more lanes by direction noted in the Phase I study were re-examined. Individual crash reports were reviewed, and any crashes that were not influenced by the restriction were removed from subsequent analysis. An empirical Bayes analysis was then used to re-assess safety using the screened crashes. Second, the operational and safety impacts of the restriction on two-lane segments of interstate were examined. Third, the effect of an enforcement campaign on compliance with the restriction for two-lane segments was determined. The crash analysis for the high-volume, three-lane segments confirmed that crashes were higher than expected after the restriction was put in place and thus were not merely the products of growing congestion. The safety and operational impacts of the restriction for two-lane interstates revealed no significant benefits, likely because the level of non-compliance with the restriction was high. With regard to the effect of the concentrated enforcement campaign, compliance improved, but the improvement was relatively modest. The study recommends that VDOT (1) pursue a legislative modification to remove truck lane restrictions on high-volume interstates with three or more lanes in each direction; (2) determine if signing could be modified to improve compliance; (3) partner with the Virginia State Police and the Virginia Trucking Association to increase compliance on the two-lane directional segments of interstate; and (4) direct a study to re-evaluate the effectiveness of the two-lane restrictions once at least 3 years of "after" crash data are available. Removal of the truck restrictions on the specified high-volume interstates should create crash reduction benefits. If crash costs are converted into dollars, an estimated $266,996 of crashes would be eliminated statewide annually through removal of these restrictions. Those costs accrue to drivers. Additional direct savings to VDOT would occur through the reduction of signing.
